Back in the 80's people thought I was nuts for keeping an emergency kit. I like having a ranger handbook in it as well and not that I can use it right now, but I also keep a small orphan .22 revolver in it.
I was left in too many places without support to not learn fieldcraft and survival skills early on. My Eagle Scout status was tested alot those days. Small amount of gear to keep warm, signal and nourish ones self with is mandatory in our world as you know these days.
Battle Field Pickup is an option for ya these days. When I worked in Bosnia the landlady I "rented " from "gave" me a pristene Thompson M1928 Sub gun , ammo marked 1941 frankford arsenal and 13 magazines. It was brand new. That was my anti-kidnappin gear for when I was home alone there.
